Hearing Health

Can someone who is hearing impaired and needs to use a hearing aid to hear higher pitches be disqualified for work in health care, even if they have fitted a stethoscope during the hearing aids and can communicate and hear both the hearing and the stethoscope?

And because college have the right to discriminate against that person on the basis of a disability?

This person has the right to work in health care.
it would be illegal for them not to give a person at work because of it.

and the college can not do it anymore.

I made my living room with an anesthesiologist who had high freq hearing loss. He had a device that vibrates when the alarm went off track when he was alerted, although he could not hear them.

It is certainly feasible, as they can do what needs to be done.
